All earthquakes from January 1, 2017 to December
31, 2017
from 1.0 and above (Richter Scale).*
Earthquake data is from USGS Earthquakes of the Week.

*California is the exception of the coverage; only earthquakes from 3.0 and
larger or
earthquakes deeper
than 17.5 kilometers were recorded. So many earthquakes
occur along the western side of
California that
it would have been just a solid blur of small circles.
However, all earthquakes in the Los Angeles
region were recorded because of the high probability of a large earth quake.
